Step 1: Bring an inch or two of water to boil in the saucepan. Mix all the ingredients thoroughly in a glass bowl, using a hand-held electric mixer until well blended.
Step 2: Place the glass bowl on top of the saucepan, and continue beating with the mixer until stiff peaks form.
Step 3: This process supposedly takes about 7 minutes, but don't bother going by the clock. When you lift up the beaters , you should see stiff peaks remaining.
Step 4: Remove the frosting from the heat, and beat it until you reach the desired consistency (this won't take long at all.).
Step 5: If you are using water instead of coffee, add a teaspoon of flavoring such as vanilla or almond and beat until it's blended in.
Step 6: Now you're ready to frost your cake.
